Application August 1, 1956, Serial No. 601,464

1 Claim. (Cl. 160-92) This invention relates to window units and it is more particularly concerned with a composite unit which may be manufactured as a Prefabricated unit ready to be set in place in a wall or ceiling as a complete portion of a building structure.

One of the objects of the invention is the provision of such a unit which is complete in itself, except for mounting in a wall or ceiling of a structure.

Auotherobject of the invention is the provision of such a composite unit which includes a permanent screen as an integral part of the assembly and in which the parts aregso arranged that the presence of the screen in no way interferes with cleaning operations of the glass portions of the window or windows.

A.4 further object of the invention is the provision of such va piefabricatedl unit which provides a rainpro'of construction by the use of inexpensive parts and arrangements thereof in relation to other parts.

A still further object of the invention is the provision of such a window unit in which the rain-proofing is effected without the use of any metal strips or weatherstripping.

A still further object of the invention is the provision of such a unit in which the windows are easy to open and which is, therefore, particularly indicated for use by aged and inrm persons, such as in homes established for such persons.

A still further object of the invention is the provision of such a unit in which the windows comprise double panes to provide heat insulating pockets and in which one of the panes is movable relative to the other.

These and other objects, advantages and features of the invention will appear more fully from the following description considered together with the accompanying drawing:

In the drawing:

Fig. l is an elevational view of an embodiment of this invention as it would appear from the interior of a building to which it may be attached.

Fig. 2 is an elevational view of the embodiment, partly broken away from the exterior of the building.

Fig. 3 is a side elevational view of the embodiment.

Fig. 4 is the upper portion of Fig. 1 on a larger scale, with parts broken away.

Fig. 5 is a broken section along the line 5 5 of Fig. l on a larger scale.

Fig. 6 is a section along the line 6 6 of Fig. 9.

Fig. 7 is a section along the line 7 7 of Fig. 10.

Figs. 8, 9, l0 and 11 are sections along the lines 8 8, 9 9, l0 10, and 11-11 respectively, of Fig. 1, using an enlarged scale.

Referring with more particularity to the drawing in which like numerals designate like parts, the embodiment illustrated comprises a main or base frame 21 which may be rectangular, as shown, consisting of side sections 22 and 23, and end sections 24 and 25, any one of which may be used as the top. In other words, the frame 21 may be oriented so that its larger dimension is either vertical or horizontal. In the drawings, the Larger dimension is vertical for illustrative purposes only.

The outer edges 26 of the frame 21 are at to set inside an opening of a building wall or ceiling (not shown) provided for it. On the ins-ide, however, the edges .are milled in step fashion resulting in the thickness of fthe frame decreasing from the exterior to the interior, substantially as shown. A plunality of such step formations are preferred, the same being designated in the drawing by the numerals 27, 28, 29, 30 and 31.

A feature of the invention is the lspecial shaping of the outermost stepped portion 27 which is beveled to provide a sloping inside edge 32, the purpose of which will ibeexplained more fully hereinafter.

The outermost edge of the base fname is a flat surface 33 not affected -by the beveled edge 32 and it acts as a marginal support for a permanently set screen sheet 34 which is placed against it and held in place by overlying holding strips 35 secured to the frame with nails 36 or any other suitable means.

As illustnated, the embodiment comprises three separate window sections, namely, an upper window section an intermediate window section and a lower window section but this is for illustrative purposes only. More or less window sections may be provided.

The upper and intermediate window sections are separated from each other by a cross piece 37, the upper edge 38 of which slopes downwardly from the interior to the exterior. The window pane itself has a frame 39 which is hinged along its bottom to the'cross piece 37 by'.

hinges 40.

The lower edge of the pane 39 has Va sloping edge 41 complementary to the edge 38 and it contains a lateral semi-cylindrical groove 42 to fit a complementary semicylindrical ridge 43 on the edge 38 that acts as a water barrier and which, in conjunction with the slope of the edges 38 and 41, keeps rain out.

The remaining outer edges of the other three sides of the pane frame 39 are stepped to fit the steps 27, 28, 29, 30 and 31 on the inner edges of the main or base frame when they are in closed position, substantially as shown.

The pane frame 39 carries :a permanently mounted window pane 44 in outer recesses 45 and as customary, it is caulked with putty or other suitable caulking compound 46. An important feature of the invention is the sloping of the edge 32 at the same angle as the outer surface 47 of the putty and contiguous thereto. As a result of this arrangement water from rain or from .a source otherwise directing it inwardly .against the sloping surface 32 will have a tendency to ow past the point between the surface and the putty in the absence of any obstruction or deviation at that point, and hence conducted to the exterior surface of the window pane. However, if some water does happen to enter nevertheless, it will be trapped by the step formations and be effectively barred.

The inside of the window pane frame 39 contains `an inside recess 48 for receiving a storm window frame 49 carrying a window pane 49A which is held in place by hinges 50 on one side and a latch 51 or other suitable means on the other side. A latch 52 or other suitable holding means is also provided for .the window pane frame 39.

To show the versatility of the invention, the intermediate window pane frame 43 is illustrated as being hinged at the top by hinges 54 to the cross piece 37. In connection with this hinged arrangement, a stepped formation is shown adjacent the hinge line together with the sloping edge 55 contiguous with putty surface 56. The cross piece 37 carries also an exterior abutment surface 57 as intermediate support for the screen sheet 34.

The `cross pie-ce 58 between the intermediate window section :and the lower window section carries stepped formations on both its upper and lower sides and an exterior abutment surface 59 as a further intermediate support for the screen sheet 34. The lower window pane l frame 60 is hinged to the bottom :sill 25 with hinges 61 .and this bottom sill may be shaped on its upper side similar to the upper side of the ycross piece 37 with a sloping edge 62 and semicylindrical ridge 63 to complement a sloping bottom edge 64 and semi-cylindrical groove 65 on the Window frame.

The storm windows of the `intermediate and lower Window sections are provided identical to that of the upper window section and the latches may be the same, as shown, or of any diferent type desired.

A unit of this type, as it will be readily apparent, is fully operable from the interior of the structure to which it is applied. The window can be opened, closed, and cleaned `on both faces of the panes, from a single position, There are no sliding members which are frequently ldiicult to 'move over each other when painted. Also, the screen sheet may remain permanently affixed because it does not in any way interfere with the operation of 'the windows or with the cleaning thereof. Also, the storm windows aire completely independent of the screens. The means for sealing against rain is effective and requires no elaborate weatherstripping as is usually required in other types of windows. The Windows also require no counterbalance Weights or springs.

Having thus described my invention, I claim:

A prefabricated screen and Window unit adapted to be set in and to form a structural part of a wall, comprising members arranged to form a base frame adapted to be placed in juxtaposition and secured directly to the wall of which it is to form a structural part, said frame having a plurality of separate openings therein from one side to the other, one side of the frame being presented as the exterior and the other las the interior, members arranged to form a first window pane frame set in each of the said openings and having its interior side substantially ush with the interior side of the base frame, means on the interior side of the base frame hingedly connecting it to the window pane frame so that the latter swings inwardly relative ,to the base frame, the members of the base frame and of the window pane frame having contacting surfaces vadjacent and parallel to the hinge line sloping outwardly from the interior to the exterior, the thickness of the members of the base frame being substantially greater than the thickness of the members of the window pane frame, whereby the members of the base frame extend beyond the members of the panef-rame, the outermost portions of said base frame members having each a flat surface parallel to .and offset `outwardly from the exterior side of the pane frame members, a screen sheet overlying said portions, and means securing said sheet to the saidl flat surfaces.
